When does your Ped start giving shots?

My DH took the LO for her 2 week checkup, which doesn't make sense because she's 3 weeks old. I asked him when she has to go back and the appointment isn't until the end of December? With my son he received his shots at 1 month. I plan on calling them tomorrow, but I thought they all started at 1 month? Different state and Dr., I don't know if that makes a difference? When is your LO getting first set of shots?
